Sticky Sessions

There is a helper script in this directory: get_instance_cookie_jars.sh

• specify number of expected instances with -e #
• specify maximum number of tries with -m #

The script will create cookie jars in the current directory, using the filename pattern cookie_jar_<instance_id>.cjar

To direct a curl request to a particular instance, specify -b <cookie_jar_file> on the curl command line.

Or, to set up a sticky session manually:

1. Get your sticky session by running:

curl -d '' dora.yourdomain.com/session -c instance_1

1. Run with a different filename for each instance, and repeat the curl command until you get a new ID

curl -d '' dora.yourdomain.com/session -c instance_2

1. Then you can target whatever instance you want for example:

curl dora.yourdomain.com/stress_testers -b instance_2
